Remote start does not work on 2010 2500HD

Postby nasty [OP] » Sep 15 2011, 5:01pm

The remote start on my 2010 GMC 2500HD does not work. The doors lock and unlock with the fob but nothing happens when the start button is pressed. It worked the previous day. There are no codes present and remote start is turned on in the DIC. Looked for a specific fuse but did not see one just for the remote system. Any help would be greatly appreciated as the closest dealer is over 300 miles away.

Have you tried a new battery in the key fob? Might be weak. Sometime weak batteries can cause strange things to occur.

You have not had a check engine light come on? That will disable it. Also check the hood, if its not completely closed it will not work.

Also note,If you start it 2x in a row with the remote and not drive the vehicle, remote is disabled until the vehicle is driven, e.g. ignition cycled on and off.

As I stated no codes present and none of the things listed in the manual that will disable are present. Battery is new and fob works door locks with no problem.

Are you pushing the lock button and then immediately pressing the start button?

Try to open and close your hood. Maybe the hood trigger didn't catch. It's a safety thing so the truck won't remote start while the hood is open.
